I purchased the Pro Series MBRP Exhaust about 5 weeks ago from an online retailer. NOT directly from MBRP. Good price-$409 delivered. The system arrived quickly but one of the middle components (the Over Axle Pipe) was damaged. The box was fine. Everything seemed to fit snugly together, though (read on). I returned it and after 30 days of waiting (not MBRP's fault), my second one arrived. The return order got lost over the holidays. Well, I assembled it this morning to make sure everything was OK. This one looked much shinier and fit together much more easily. So I decided to completely assemble it. Every single connection point will not fully clamp together snugly no matter how far I crank the clamps down. The pipes are getting OVAL in shape as I crank down the clamps. The variances/tolerances between the flared ends of the pipes and where they slide into each other are just too big. The clamps appear to be too big as well. The Tail Pipe Tip also won't ever completely clamp on. Is this just normal fitment issues that come with all aftermarket exhaust systems? Did those of you who purchased one of these have this many problems? I don't intend to bash MBRP, but I'm REALLY disappointed and frustrated. Could use a little guidance/advice here...

Mine went on easily. I was surprised but my jeep felt a bit quicker with the MBRP. I figured with a DPF it wouldn't hurt but wouldn't be very noticeable. I was shocked. Its not a huge difference but every bit counts in my eyes.

Try moving the clamps right to the ends of the expansions and make sure the bolt is over one of the slots...if this does not work,and you're having issues getting this tight, do not hesitate to call me directly at MBRP inc. at 1-888-636-7223 ext. 202. Hope this helps.

Thank you. Haven't had a chance to work on it much further since. I'll try that next. I really like the workmanship of the pipes overall. It's the clamp on components that are giving me fits this time(clamps and tailpipe). I'll call you this week. Thanks for offering to help.
